This invention relates to improvements in receptacles and is directedmore particularly to improvements in cartons which are foldable to provide a receptacle.

The principal objects of the' invention are the provision of a carton blank which is adapted for setting up to provide a receptacle for the glass filler of a thermos bottle.

Such fillers are very fragile and have a nipple or nipples depending from the lower side thereof which is easily broken off so that the filler becomes useless.

According to the novel features of this invention, a carton blank isprovided which is readily set up to provide a receptacle particularly adapted for holding a thermos bottle filler and is characterized by means for holding the filler from contacting with the side walls of the receptacle and means cooperating therewith for holding the lower end of the filler and nipple depending therefrom from contacting with the receptacle closing means at the lower end thereof.

With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the description proceeds. the invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:

Fig. 1 is a plan view of a carton blank embodying the novel features of the invention;

Fig. 2 is a sectional elevational view through a receptacle formed by blank shown in Fig. 1;

Fig. 3 is a sectional plan view on the line 3-3 of Fig. 2; v

Fig. 4 is a sectional elevational view on. the line d-4 of Fig. 3; and

Fig. 5 is aperspective view of the lower portion of the receptacle shown in Figs. 2, 3 and 4.

Referring now to the drawings more in detail, the invention will be fully described.

A carton blank is shown in Fig. '1 which has four panels 2, 4, 5 and 8 that provide longitudinal side walls for a receptacle. The panel 6 has a longitudinal tab ill which is secured to an adjacent longitudinal edge of panel 4 and the panels are hinged at I2 to facilitate setting up the blank as shown in Fig. 2.

End flaps I 4 are hinged to upper ends of panels .4 and 8 and a closure flap it having a tuck l8 hinged thereto is hinged to the upper end of panel 8.

The end flaps l4 are swung inwardly and the flap is is swung thereover to close the upper end of the receptacle, as shown in Fig. 2.

The panels 2, 4, 6 and 8 are provided with score lines 20 parallel to longitudinal edges there- 3 Claims. (Cl. 229-39) of and with transverse slits 22 providing panels 24 which are swingable inwardly relative to the walls as shown in Figs. 2 and 3.

Other slits 26 and score lines 28 are provided to form lips 30 on the upper ends of panels 24, which are swingableinwardly, as shown in Fig. 2.

A lower closure flap 34 is hinged at 35' to the lowerend of panel 2 and supports 38 are hinged as at 40 to lower ends of panels 4 and 8. A tuck 42 is hinged at 44 to the outer free end of flap 34.

The flap 34 and adjacent portion of panel 2 are provided with spaced slits 48 and score lines 50 and 52 forming a platform 54 and a support 56 which are relatively hinged at 58, see Fig. 1.

The portion of theplatform indicated by 54' adjacent the score line 50 is of less width than the main body of the platform and theportion 56' of the support adjacent the hinged line 58 has converging sides, as shown in Fig. 1. The supporting flaps 38 are provided with lips 38' also as shown in Fig. 1. a

With the walls in the set-up relation shown in Figs. 2 to 5 inc., the supporting flaps 38 are swung inwardly and the flap 34 is swung thereover with the tab 42 disposedagainst wall 5.

The platform 54 and support 56 are swung inwardly relative to wall 2 and flap 34 and against supporting flaps 38 so as to swing them upwardly towards their respective walls.

The platform 54 assumes the horizontal position and the support 56 assumes the vertical position, shown in Fig. 2. The upper edges of the supporting flaps 38 underlie opposite side edges of the wider part of the platform 54. The ears 38' of the flaps 38 abut opposite sides of the narrow part54 of the platform so that they will not swing inwardly.

Thus the platform is held and supported by its connection with the wall 2 and support 56. I

and flaps 38 which underlie opposite sides thereof and provides a pocket or well 60 between support 56 and wall 6. v A thermos bottle filler is inserted in the receptacle so that its bottom rests on the platform 54 and the nipple on the lower side thereof is disposed in the pocket or well 60. The panels 24 in the position shown in Figs. 2 and. 3 provide inwardly extending projections at the corners of the receptacle for engaging the sides of the filler toprevent said sides fromcontacting with the side walls of the receptacle. The lips 30 extending from the panels 24 overlie the upper inwardly curving portion of the filler to prevent upward movement thereof.

Thus the platform supports the filler upwardly from the closure flap '34, the filler is held out of contact with the walls by the panels and is held against upward movement. The several components cooperate to position the filler in such a way as to protect it against blows or shocks applied to the carton.

all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.
